Allow it to air dry fully before storing. In the future put the camera in a plastic bag before going outside and let it cool to the outside temperature before removing. Do the same before taking the camera back inside and let it warm up before removing from the bag. Enough mositure inside the camera can cause the shell or gears to corode or rust.
